The researchers believe the […]

Ergothioneine is a natural amino acid with antioxidative properties. It prevents cellular stress, which can lead to brain diseases, neurological damage, and cancer. In rats and roundworms, research shows that ergothioneine has promising effects in preventing neurodegenerative diseases such as dementia and Alzheimer’s. Also, it has been reported that patients […]

Triple-negative breast cancer is aggressive cancer, one that’s likely to recur and to metastasize. It’s also quite diverse at the molecular level, and doctors currently don’t have a good method for determining which drugs are likely to work against each patient’s unique cancer. Sometimes a drug will work well against […]

The ability to synchronize behavioral, morphological and other transitions with the seasons is integral to the life cycle of most insects. A research team led by biologists at Tufts University has found two genes that may allow some insect species to survive climate change by adjusting their biological annual clocks, while others […]

A Rutgers-led team has created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders. The technology, which features unique graphene and gold-based platform and high-tech imaging, monitors the fate of stem cells by detecting genetic material (RNA) […]

The human brain has some remarkable capabilities – including the ability to block cancer drugs from effectively reaching cancer cells in the brain. The greatest obstacle when it comes to treating cancer that has spread to the brain is the blood-brain barrier, the brain’s natural defense mechanism that is a […]

Mitochondria burn oxygen and provide energy for the body. Cells lacking oxygen or nutrients have to change their energy supply quickly in order to keep growing. Scientists from the Max Planck Institute for Biology of Ageing have now shown that mitochondria are reprogrammed under depleted oxygen and nutrients. Tumours of […]

Brain-computer interfaces (BCI) work on the principle that measurable changes in electrical brain activity occur just by thinking about performing a task. Signals can be read, evaluated, and then converted into control signals via a machine learning system, which can then be used to operate a computer or a prosthesis. […]

Hard-to-study mutations in the human genome, called short tandem repeats, known as STRs or microsatellites, are implicated in the expression of genes associated with complex traits including schizophrenia, inflammatory bowel disease and even height and intelligence. That’s the conclusion of a study published in the journal Nature Genetics by a […]

The protein adipsin helps protect insulin-secreting cells called pancreatic beta cells from destruction in type 2 diabetes, according to a new study by researchers at Weill Cornell Medicine and NewYork-Presbyterian.
